The results of a research project (2017-2019) carried out by the author on the models and representations on science and on its labor and professional field in groups of students of the Methodology Department of the Psychopedagogy Career at the National University of San Martin (Argentina), based on diagnostic evaluations (questionnaires), are presented. The results obtained show typical gaps in such models of personal science, respect for current socio-anthropological conceptions (Latour, cultural studies on science), which are corrected by working with conceptual networks and specific didactic and evaluative strategies.
